  A copper-catalyzed amino lactonization of unsaturated carboxylic acids has been achieved as well as the analogous intermolecular three-component amino oxygenation of olefins. The transformation features mild conditions and a remarkably broad substrate scope, offering a novel and efficient approach to construct a wide range of amino lactones as well as 1,2-amino alcohol derivatives.

  work, an asymmetric copper‐catalyzed radical multi‐component cascade reaction of an unsaturated carboxylic acid, aryldiazonium tetrafluoroborate, and DABCO⋅(SO2)2 (DABSO) has been developed for the enantioselective synthesis of sulfonyl lactones. In this reaction, this SO2 surrogate, DABSO was applied for the first time in the construction of chiral compounds. This multiple‐step asymmetric radical reaction

  An expansion of methodologies aimed at the formation of versatile organonitriles, via the intramolecular aminocyanation of unactivated alkenes, is herein reported. Importantly, the need for a rigid tether in these reactions has been obviated. The ease-of-synthesis and viability of substrates bearing flexible backbones has permitted for diastereoselective variants as well. We demonstrated the utility

  本文报道了旨在通过未活化烯烃的分子内氨基氰化形成多功能有机腈的方法的扩展。重要的是，在这些反应中不需要刚性系绳。带有柔性主链的底物的合成容易性和生存能力也允许非对映选择性变体。我们通过形成吡咯烷酮、哌啶酮、异吲哚酮和舒尔坦证明了这种方法的实用性。此外，还证明了这些基序随后转化为医学相关分子。双交叉 13C 标记实验与完全分子内环化机制一致。氘标记实验支持涉及跨烯烃的顺式加成的机制。
